Synthesis and coordination chemistry of a water-soluble verdazyl radical. structures and magnetic properties of M(H2O)2(vdCO2)2·2H2O (M = Co, Ni; vdCO2= 1,5-dimethyl-6-oxo-verdazyl-3-carboxylate)
occupy a pseudo-equatorial position related to the existence of an intramolecular hydrogen bond where the substituent acts as an acceptor. 2-Hydroxyphenyl moieties occupy a pseudo-axial position related to the existence of an intramolecular hydrogen bond where the substituent acts as a donor. In the sole example where an intramolecular hydrogen bond is not present (2-imidazolyl derivatives), the preference

The synthesis of a verdazyl radical with a carboxylate substituent renders the radical highly soluble in water, thereby permitting the aqueous synthesis of Ni(II) and Co(II) verdazyl complexes which have been structurally and magnetically characterized.
